Can't remove Items in PaperUI and Habmin

While trying to debug a rule problem, I removed my ZWave, DSC and OpenSprinkler bindings from the system, without first removing all associated Things and Items. When I added the Bindings again, my controls did not re-appear. I then tried to delete everything and start over from scratch. However, now I cannot delete two remaining items (neither in PaperUI nor in Habmin). This is what I am seeing in logs:

2017-05-23 22:19:53.221 [INFO ] [thome.io.rest.core.item.ItemResource] - Received HTTP DELETE request at 'items/Zone1_ZoneStatus' for the unknown item 'Zone1_ZoneStatus'.
2017-05-23 22:19:55.202 [INFO ] [thome.io.rest.core.item.ItemResource] - Received HTTP DELETE request at 'items/OpenSprinkler_Station01' for the unknown item 'OpenSprinkler_Station01'.

Both items are still visible in PaperUI and in Habmin.

Just found loosly related problem in the forum where the suggestion was to restart OH2.


I tried that, and the Items disappeared.
